Assume that Home and Foreign produce only two goods - Oil and Corn. Home has 900 units of labour available. In Home, the unit labour requirement in Oil production is 6 and in Corn production it is 2. On the other hand, Foreign has 1800 units of labour available. Foreign's unit labour requirement in Oil production is 18, while in Corn production it is 3.

d. Construct the world relative supply curve using the relative price and relative quantity of oil. Explain clearly the steps of deriving world relative supply curve in details. Illustrate it on a diagram. [3 points]
